I have my files spread between the main drive and a volume that is mounted most of the time. Spotlight is enabled and properly indexing both of them.
When searching through the top right spotlight menu, only results from the drive show up.
When searching from a finder window, I get two options in the header for where to search "This Mac" or "My Volume". "This Mac" (the default) only shows results from the drive, while "My Volume" only shows results from the volume...
How can I get all results, across both the drive and the mounted volume, to show up in a single list?
[I should mention that for merged results limited to filename searches a solution could be to use an app called Alfred. However Alfred doesn't apply search queries to file contents as does the regular spotlight search.]
